Data Sources and Metrics
The 5th edition of the Research.com Best Mathematics Scientists in Lebanon Ranking is constructed on a robust foundation of bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple additional reputable data sources. These platforms provide comprehensive and up-to-date metadata on scholarly publications and citations, which are critical for the development of citation-based metrics. The bibliometric data used to devise these metrics were collected on January 12, 2026, ensuring that the ranking reflects the most recent research outputs and impact.
A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined variant of the traditional H-index. The D-index exclusively considers publications and citations pertinent to the discipline under examination—in this case, Mathematics—thus providing a focused metric of disciplinary research influence.
Scope of Research and Inclusion Criteria
The ranking evaluates an extensive dataset comprising 279,971 scientist profiles gathered from various bibliometric sources and spanning all scientific disciplines. From this broad pool, 2 scientists specifically identified within the field of Mathematics in Lebanon were examined in detail. To qualify for inclusion in the ranking, a researcher must meet several stringent criteria:
- Possess a D-index of at least 30, reflecting substantial impact within the discipline.
- Ensure that the majority of their tiered publications are situated in the area of Mathematics.
- Have awards and notable achievements in Mathematics, further validating their disciplinary excellence.
The threshold for the D-index is adjusted in increments of 10 based on the estimated total number of scholars within each discipline, a strategy designed to capture the top 1% of leading researchers in the field. Additionally, to assure disciplinary relevance, the difference between a scientist's general H-index and D-index must not exceed 30%, ensuring a high degree of alignment with Mathematics-specific scholarship.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully capture the multifaceted contributions of scholars, the Research.com team undertook meticulous manual verification of all scientist profiles. This process involved cross-referencing individual publication records against a wide array of trusted sources to confirm accuracy and ensure data integrity.
While the number of publications in prestigious journals and leading conference proceedings does not directly influence the ranking position, it serves as an important secondary signal of a scientist’s scholarly contributions within their field.
The final ranking positions are established using the validated D-index scores derived from OpenAlex and CrossRef, which are among the most prominent and respected bibliometric databases accessible to the research community.
